The chassis module 300 is connected to the lower side of the frame 100, and the support module 400 is connected to the upper side of the frame 100. The vehicle body can be a part of a garbage sweeper, and can enable the garbage sweeper to achieve a road surface sweeping function or a carrying function.

The racking module 400 includes a racking plate 410, on which racking plate 410 a carrier or trash can be placed. The cargo can be goods or express delivery and the like.

When the vehicle body is used, the purpose of the vehicle body can be changed according to needs, so that the vehicle body can realize multiple functions. For example, when the road surface needs to be cleaned, a garbage can may be placed on the supporting plate 410, the road surface may be cleaned by the cleaning module 200, and the garbage may be collected in the garbage can. When the cleaning work is completed and the garbage can is in an idle state, the garbage can placed on the supporting plate 410 can be taken down, and the carrier is placed on the supporting plate 410 for transportation. And, the cargo also can be the garbage bin, realizes that rubbish transports through the automobile body delivery garbage bin.

Different objects are placed on the bearing plate 410, so that different functions of the vehicle body can be realized, the vehicle body has higher flexibility, the utilization rate of the vehicle body is improved, and the resource waste is reduced.

Preferably, a cleaning module drive (not shown) is also provided. The cleaning module 200 is rotatably connected to the frame 100, and the cleaning module 200 is connected to a power output end of a cleaning module driving member. The cleaning module 200 can be moved to adjust its height by the cleaning module drive.

When the road surface needs to be cleaned, the cleaning module 200 can be driven to move by the cleaning module driving part, so that the height of the cleaning module is reduced, the cleaning module is in contact with the road surface, and the road surface is cleaned. When it is needed to transport the cargo, the sweeping module 200 may be driven by the sweeping module driving member to move, so as to ascend and separate from the road surface, thereby reducing the friction force between the road surface and the sweeping module.

In addition, a garbage collection component such as a suction piece and a rolling brush can be arranged to collect the garbage. Similarly, the refuse collection member may also be moved in a vertical direction into and out of contact with the road surface. When the garbage collection device is not needed to be cleaned, the garbage collection device is lifted upwards to avoid friction with the ground, and when the garbage collection device is needed to be cleaned and collected, the garbage collection device is put down.

Specifically, referring to fig. 3, the cleaning module 200 includes a fixing frame 210, the fixing frame 210 includes a cross bar 211, a vertical bar 212 and a rotating bar 213, the cross bar 211, the vertical bar 212 and the rotating bar 213 are fixedly connected to each other, and two ends of the vertical bar 212 respectively extend out of the cross bar 211. Both sides of the holder 210 are provided with a first cleaning brush assembly 230 and a second cleaning brush assembly 280, which can contact with a road surface for cleaning. The fixing frame 210 is connected with the power output end of the cleaning module driving member, the rotating rod 213 in the fixing frame 210 is rotatably connected with the frame 100, and the fixing frame 210 can be driven by the cleaning module driving member to rotate up and down relative to the frame 100, so as to realize the lifting and falling of the cleaning module 200.

Further, a first rope 290 is included, and the first rope 290 may be a steel wire rope. The cleaning module driving part can be a linear motor, an air cylinder or an electric push rod and other common driving parts. One end of the first rope 290 is fixedly connected to the fixing frame 210, and the other end is fixedly connected to the power output end of the cleaning module driving member, and the fixing frame 210 can be rotated up and down by pulling or releasing the first rope 290 through the cleaning module driving member. Of course, when the fixing frame 210 is put down, it can be directly dropped by its own weight.

Preferably, the first cord 290 may be coupled to the fixing frame 210 by passing around a pulley. By providing a pulley, the first rope 290 can be pulled or paid out more smoothly.

Referring to fig. 2, preferably, a support plate driving member 420 is disposed below the support plate 410, and the support plate 410 is connected to a power output end of the support plate driving member 420. When loading and unloading objects on the support plate 410, the support plate 410 can be driven by the support plate driving member 420 to move in the vertical direction to adjust the height thereof, so as to reduce the difficulty of loading and unloading. The support plate driver 420 may be a cylinder, a linear motor, or an electric push rod.

Specifically, during loading, the support plate 410 is driven by the support plate driving member 420 to move downward, and the vehicle body is moved so that the support plate 410 reaches under the object. Then, the support plate 410 is driven to move upward by the support plate driving member 420, so that the top of the support plate 410 is brought into contact with the object and lifted up, thereby completing the loading. During unloading, the support plate 410 is driven to move downward by the support plate driver 420, and the top of the support plate 410 is separated from the object, contrary to the above-described process. Then, the vehicle body is moved to pull the support plate 410 away from the object. It should be noted that, when loading and unloading are performed in the above manner, a certain receiving space is required for the bottom of the object to enter the supporting plate 410.

The loading and unloading device is very convenient to use, manual carrying is not needed, labor can be saved, and efficiency is high.

Preferably, a matching guide assembly may be provided on the support plate 410 and the object to guide the object. For example, a sliding track or a sliding groove may be provided on the supporting plate 410, and a pulley or a slider may be installed on the bottom of the object. When loading, through the cooperation of direction subassembly, the motion process when can make object loading and uninstallation is more stable, is difficult for producing offset.

Preferably, the supporting plate 410 is further provided with a first limiting portion 411 and a second limiting portion 412 for limiting the object. The first position-limiting portion 411 is a protrusion protruding upwards from the top surface of the supporting plate 410, and after an object is placed on the supporting plate 410, the side surface of the object is blocked and limited by the first position-limiting portion 411. The side wall of the support plate 410 is provided with an accommodating hole 413, and the second limiting portion 412 is rotatably connected with the support plate 410 and can be extended outwards in a rotating manner or retracted inwards in the accommodating hole 413. As mentioned above, the bottom of the object needs to have a certain receiving space for the supporting plate 410 to enter. The usual way is to mount a support frame on the bottom of the object to lift it. When an object is supported on the supporting plate 410, the second limiting portion 412 can be pulled out, so that the supporting plate blocks and limits the supporting frame at the bottom of the object. In addition, the bottom of the support frame can be provided with rollers so as to be convenient for moving.

Through foretell limit structure, the rocking and the offset of object when can reduce the automobile body motion. Particularly, at the moment when the vehicle body starts or stops, the forward tilting or backward tilting due to the inertia thereof can be reduced.

Preferably, a non-slip pad may be further provided on the support plate 410 to increase friction between the object and the support plate 410 so that it is not easily moved.

Preferably, a racking module slide 430 and a racking module slide 440 are also provided. The bearing module slide rail 430 is fixedly connected to the frame 100, a vertical plate is fixedly connected to an end of the bearing plate 410, and the bearing module slide block 440 is fixedly connected to the vertical plate. When the bolster plate 410 moves in the vertical direction, the bolster module slide 440 will slide along the bolster module slide rail 430 for guidance. Of course, the positions of the sliding block and the sliding rail can be changed, or the guide rod and the guide sleeve can be used for guiding.

In addition, the supporting plate 410 is further provided with a through hole 414, which can be provided with a suction pipe, a blower and other components, and when the cleaning module 200 performs cleaning, the suction pipe, the blower and other components draw the garbage into the garbage bin. The through-hole 414 described above may be used to pass a straw therethrough.

Referring to fig. 8 and 9, a schematic structural diagram of the chassis module and the frame and a partial structural diagram of the chassis module in fig. 1 are respectively shown. In the chassis module 300, each wheel 310 is provided with a hub motor (not shown) inside for driving the wheel to move. Compared with the common two-wheel drive, the four-wheel drive can ensure that the power of the vehicle body is more sufficient and the climbing capability is stronger. When the four-wheel drive type automobile is used in rainy and snowy days, the probability of wheel slip can be reduced by four-wheel drive, and the safety of the four-wheel drive type automobile is improved. In addition, since the in-wheel motor is directly arranged inside the wheel 310, a transmission shaft and a transmission part are not required to be arranged between the front axle and the rear axle, the space in the vehicle is larger, and the transmission efficiency is higher.

Preferably, the chassis module 300 includes a front steering gear 320 and a rear steering gear 330, and both wheels 310 on the front side are connected to the front steering gear 320, and the front steering gear 320 can steer the wheels. Both wheels 310 on the rear side are connected to a rear steering gear 330, which can be steered by the rear steering gear 330. The two steering gears are arranged, so that the front wheels and the rear wheels can independently steer, and compared with a single steering gear, the flexibility of turning the vehicle body can be improved, the turning radius of the vehicle body is reduced, and the vehicle is convenient to drive in narrow areas.

The wheel 310 is provided with a connecting frame 311, the top end of the connecting frame 311 is connected with the first bracket 350, and the bottom end is connected with the second bracket 360. The first bracket 350 and the second bracket 360 are connected to the frame 100. First support 350 is "A" font, including two down tube 351 and a stiffener 352, two down tube 351 all with link 311 go up same position and be connected, and connect through stiffener 352 between two down tube 351, stiffener 352 can improve first support 350's intensity. And, an elastic member 340 is provided between the second bracket 360 and the frame 100. Alternatively, an elastic member may be provided between the first bracket 350 and the frame 100. The elastic member 340 may be a hard spring.

The elastic member 340 is arranged between the wheel 310 and the frame 100 to absorb shock and reduce the shaking of the vehicle body. When the road surface is uneven, the four wheels 310 can be in contact with the road surface, and no wheel is suspended. For example, one of the wheels 310 is located in a pit, and the elastic members 340 at the other three wheels 310 will be compressed, so that the four wheels 310 all grip the road surface, and the running is more stable.

Referring to fig. 3 to 7, how the cleaning module 200 cleans the road surface will be described. Fig. 4 to 7 are a partial structural view of the cleaning module of fig. 3 and a view illustrating a state where the first cleaning brush assembly is retracted, respectively. The first cleaning brush assembly 230 includes a first cleaning brush 231 and a cleaning brush driving member 232, the first cleaning brush 231 is connected to a power output end of the cleaning brush driving member 232, and the first cleaning brush 231 can rotate under the driving of the cleaning brush driving member 232 to clean the road surface. The cleaning brush driving member 232 may be a common driving member such as a rotary motor or a rotary cylinder. Preferably, a steering engine can be selected to reduce weight.

The first cleaning brush 231 includes a bristle attachment plate 2311 and a plurality of bristles, which are fixed to the bottom of the bristle attachment plate 2311. The bristles need to have certain hardness to improve strength, are not easy to damage when encountering hard objects such as stones and the like, and are easier to remove adhered objects on the road surface. Because the bristles are in contact friction with the road surface for a long time, the bristles are also required to have good wear resistance so as to be not easy to wear and have long service life. In addition, the brush hair should have certain elasticity, and when the first cleaning brush 231 touches an obstacle, the brush hair can elastically deform to sweep over the obstacle, so as to prevent the brush hair from being damaged.

The second cleaning brush assembly 280 is fixed at the side wall of the cross bar 211. The second cleaning brush assembly 280 is identical to the first cleaning brush assembly 230, and thus, will not be described in detail.

Preferably, the first cleaning brush assembly 230 is also capable of rotating left and right to be in an opened or retracted state. The first cleaning brush assembly left and right rotation driving member 220 is positioned at the top of the cross bar 211 and is fixedly connected thereto, and the first cleaning brush assembly 230 is connected to a power output end of the first cleaning brush assembly left and right rotation driving member 220. The first cleaning brush assembly left and right rotation driving member 220 can drive the first cleaning brush assembly 230 to rotate in a first rotation plane relative to the holder 210, so that the first cleaning brush assembly 230 is in an open state as shown in fig. 3, or in a retracted state as shown in fig. 6. The first plane of rotation here is a plane parallel to the top surface of the vertical bar 212. The first cleaning brush assembly left and right rotation driving member 220 may be a motor or a cylinder.

When the first cleaning brush assembly 230 is opened, it is farther from the holder 210, and can clean the distal region; when the first cleaning brush assembly 230 is retracted, it is closer to the holder 210, and the proximal region can be cleaned. Therefore, when the cleaning module is used, the cleaning area can be changed as required to adapt to different cleaning requirements. If more garbage exists in the remote areas, the first cleaning brush assembly 230 can be opened to clean the areas; if more debris is present in the closer area, the first cleaning brush assembly 230 can be retracted to clean the area, thereby optimizing the cleaning effect.

Further, the cleaning module further includes a connecting rod assembly 240, and the power output end of the first cleaning brush assembly left-right rotation driving member 220 and the first cleaning brush assembly 230 are connected to the connecting rod assembly 240. The first cleaning brush assembly left and right rotation driving member 220 drives the first cleaning brush assembly 230 to rotate relative to the holder 210 through the link assembly 240.

Specifically, the first cleaning brush assembly left and right rotation driving member 220 may be an electric push rod or a linear motor, which pushes a rod in the connecting rod assembly 240 to rotate, so as to rotate the first cleaning brush assembly 230. The linear motion output from the first cleaning brush assembly left and right rotation driving member 220 can be converted into the rotational motion of the first cleaning brush assembly 230 by the link assembly 240.

The link assembly 240 includes a first link 241, a second link 242, and a third link 243. One end of the third link 243 is fixedly connected to the cleaning brush driving member 232 of the first cleaning brush assembly 230, and the other end is connected to the connecting member 250. The connecting member 250 is rotatably coupled to the cross bar 211 to be rotatable with respect to the cross bar 211 in a first rotational plane. That is, the third link 243 is rotatably connected to the cross bar 211 by the connection member 250. One end of the second link 242 is rotatably connected to the third link 243, and the other end is rotatably connected to the first link 241. The second connecting rod 242 and the third connecting rod 243 are connected through a spherical hinge, and the second connecting rod 242 and the first connecting rod 241 are connected through a spherical hinge, so that the freedom degree of movement is ensured. One end of the first link lever 241 is rotatably connected to the second link lever 242, and the other end is rotatably connected to the power output end of the first cleaning brush assembly left and right rotation driving member 220. The first link lever 241 is rotatably connected to the cross bar 211, and the connection position is located between the connection position of the first link lever 241 and the second link lever 242, and the connection position of the first link lever 241 and the power output end of the first cleaning brush assembly left-right rotation driving member 220. The connecting member 250 and the first connecting rod 241 are rotatably connected to the cross bar 211 through the same rotating shaft.

When the telescopic end of the left and right rotation driving member 220 of the first cleaning brush assembly extends out, the first connecting rod 241 is driven to rotate counterclockwise relative to the cross bar 211, and the second connecting rod 242 and the third connecting rod 243 are driven to rotate counterclockwise relative to the cross bar 211. The first cleaning brush assembly 230 fixedly connected to the third link 243 is gradually opened outward from the state shown in fig. 6 to the state shown in fig. 3 as it is rotated counterclockwise.

When the first cleaning brush assembly rotates the retractable end of the driving member 220 to retract, the first connecting rod 241 is driven to rotate clockwise relative to the cross bar 211, and the second connecting rod 242 and the third connecting rod 243 are driven to rotate clockwise relative to the cross bar 211. The first cleaning brush assembly 230 fixedly coupled to the third link 243 is then rotated clockwise to be retracted inward from the state shown in fig. 3, and gradually reaches the state shown in fig. 6.

It should be noted that fig. 3 and fig. 6 are schematic diagrams illustrating the first cleaning brush assembly 230 at two extreme positions, respectively, and actually, the position of the first cleaning brush assembly 230 may be between the states shown in fig. 3 and fig. 6.

Preferably, the second link 242 may be an air spring capable of being elastically deformed in a length direction. In the cleaning process, if the first cleaning brush assembly 230 touches an obstacle, the second link 242 can be retracted to prevent the first cleaning brush assembly 230 from rigidly contacting the obstacle, which can protect the first cleaning brush assembly 230 and make it less prone to damage.

Referring to fig. 7, preferably, the cleaning module further includes a first cleaning brush assembly up-and-down rotation driving member 260, the first cleaning brush assembly up-and-down rotation driving member 260 is fixedly connected to the connection member 250, and an end of the third link 243 is rotatably connected to the connection member 250. The third link 243 can be driven to rotate in the second rotation plane with respect to the link 250 by the first cleaning brush assembly up-down rotation driving member 260 to adjust the height of the first cleaning brush assembly 230. The second rotation plane is a plane perpendicular to the first rotation plane.

When the first cleaning brush assembly 230 is lifted, the first cleaning brush assembly 230 has a height greater than that of the second cleaning brush assembly 280, and thus can be used to clean a location having a height difference, for example, a step on a roadside. Further, when the first cleaning brush assembly 230 is lifted, the dimension of the vehicle body in the forward direction can be reduced.

Preferably, the linkage assembly 240 further includes a fourth link 244, and the fourth link 244 is equal in length to the third link 243 and parallel to each other. The fourth link 244 is positioned below the third link 243, and has one end fixedly connected to the first cleaning brush assembly 230 and the other end rotatably connected to the connecting member 250. Thus, when the first cleaning brush assembly up-and-down rotation driving member 260 drives the third link 243 to rotate relative to the connecting member 250, the fourth link 244 rotates synchronously therewith, and the third link 243 and the fourth link 244 can form a parallelogram mechanism, so as to improve the stability of the rotation process of the first cleaning brush assembly 230. In addition, the fourth link 244 may be located above the third link 243.

Further, a second rope 271 is included, and the second rope 271 may be a steel wire rope. The first cleaning brush assembly up-down rotation driving member 260 may be a linear motor, an air cylinder, an electric push rod, or other common driving components. One end of the second rope 271 is fixedly connected to the power output end of the first cleaning brush assembly vertical rotation driving member 260, and the other end is fixedly connected to the third link 243. The third link 243 is rotated up and down by pulling or releasing the second rope 271 by the first cleaning brush assembly up and down rotation driving member 260. Of course, when the first cleaning brush assembly 230 is dropped, it may be dropped by its own weight.

Preferably, a pulley 272 is further provided, and the second rope 271 is connected to the third link 243 while passing around the pulley 272. By providing the pulley 272, it is possible to make the second rope 271 more smooth when being pulled or paid out. Further, a plurality of pulleys 272 may be provided, and the second rope 271 is connected to the third link 243 while sequentially passing around the plurality of pulleys 272.

The cleaning module 200 has more modes to select when cleaning. Specifically, if it is only necessary to clean a region near the fixed frame 210, and the region is not so much garbage that it is easy to clean, the first cleaning brush assembly 230 may be lifted up and cleaning may be performed only by using the second cleaning brush assembly 280. If it is necessary to clean only the area near the holder 210, which is not easily cleaned due to much dust, the first cleaning brush assembly 230 may be lowered and retracted to perform cleaning simultaneously with the second cleaning brush assembly 280 and the first cleaning brush assembly 230. If the cleaning is required in both the area near and far from the holder 210, the first cleaning brush assembly 230 may be lowered and opened, and the cleaning area may be enlarged by using the first cleaning brush assembly 230 and the second cleaning brush assembly 280 to perform the cleaning simultaneously.

Preferably, the first cleaning brush assembly 230 may be in a lowered state all the time during the cleaning process, and the first cleaning brush assembly 230 is continuously driven to rotate by the first cleaning brush assembly left and right rotary driving member 220. Therefore, the garbage can be collected towards the inner side while being cleaned, so that the garbage can be collected more easily.

In another embodiment, a garbage sweeper is provided, which comprises the multifunctional vehicle body. Because the cleaning module 200 can be lifted and the bearing plate 410 can bear different objects, the garbage sweeper can realize different functions, has higher flexibility, can improve the utilization rate and reduce the resource waste. Moreover, the vehicle body is integral, and compared with a semi-trailer type of a conventional garbage sweeper, the vehicle body does not need to finish complex installation work, and the turning difficulty is lower.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
